Matt, Charlotte and Steve are in Perthshire, where Matt visits Cultybraggan, a former prisoner of war camp that is now a thriving community of artisans, craftspeople and food producers. He hears about its past and meets people who remember it during wartime. Charlotte jumps in a kayak and takes to the water on a wildlife safari. She’s goes beaver spotting and hears how they’re becoming a big tourist attraction. She also tries her hand at stand-up comedy when she meets 'Farmer Jim' Smith, the farmer turned comedian famed for his wry look at the farming life. Steve meets the ladies growing tea in the south Highlands and learns the art of making the perfect cuppa, Tom looks at the hidden threat from microplastics in animal feed, and Adam is in Kent meeting the blackcurrant farmer rising to the challenge of climate change.
